报告摘要：
We study a liner shipping network design problem to optimize regularship rotations for transporting containerized cargo between seaports. Theobjective is to maximize carrier profit by balancing revenue from satisfieddemand against operating and transshipment costs. We introduce a set-partitioning-like formulation to capture key service components, whichcontains numerous rotation-dependent variables and constraints, making itchallenging to solve even for its linear programming relaxation. To tackle this,we propose a simultaneous column-and-row generation solution method withnovel speed-up techniques. Integrating it into a branch-and-price algorithm.we develop an exact method for LSND and test it on two variants withdifferent rotation configurations.
